CAST-*Irion CHAIR.

Slpecieation of Letters iPatentNo. 5,317, October 2,

ToaZZ whomz't may concern.' j f .s xBeit knownmthat I, JORDANL. Mo'r'r, of thel city, county, and State of NewYork, have inventedfavnewand useful Improvement in Cast-IronfChairs, Stools,` &c`.', and that the following yisa full, clear, and eXact description of the principle or character which distinguishes itfrom all otherthings before known and of the Amanner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective representation of my improved chair supported on three` legs; Fig. 2, a like representation of my improved chair on a hollow pedestal for gardens; Fig. 3 is a plan of the same; Fig. 4:, a vertical section taken at the line (X X) of Fig. 3; and Fig. 5 another vertical section of the same. taken at the line (Z, Z) of Fig. 3.

est depression the lines radiating therefrom in all directions shall curve upward'to the rim or outer edge of they seat to fit the parts of the body and expose a larger surface kfor the support of the body than by any other form heretofore given. And also in combining with this concave form making the seat with perforations for the discharge of water. The second part of my invention consists in casting a circular depression in the deepest part of the concave seat, and

below the curved plane thereof to admit-ofl securing the spindle of the pedestal on which the seat turns, which depression is covered with a plate that completes the curved part of the seat, when this lis combined with aperturesmade through the upper plate or disk ofthe pedestal or Vstand through which the seat and covering plate are riveted together, and through which also the water that may leak through the oints ofthe seat and covering plate may discharge itself. And the third part of my invention consists in making the pedestal hollow and larger at the lower` end and securing it to a pile or stake drivenin the ground.

In the accompanying drawings (a) represents the seat of the chair with a rim b) which is largest at the lower edge to' admit of intidingad made with the upper tage. all on the same plane, The upper surface is concave ory dishred, the point of greatesty depression being at (c) rand nearerA the back than the frontedge that the person-sitting` on it may ybe so far backlyas to obtainv a better support for the. back against` theV back (d) of the chair, and to makethecurve of the back part of the seat more sudden/or abrupt than the front-that it may be better adapted to the, anatomy of the body, the abruptness `of the curves being gradually less from the back to the front. At the back the seat runs in a Vsingle curve from the point of greatest depression to the rim, as at (et) Fig. 5, and at thefront by a double curve, so thatas it approaches the rim the. rim, and from the back kto the front these curves gradually rung and lose themv selves in one another.

The seat is cast with holes through it to form a grating so that water falling on it maybe dischargedat once. 'The under surface is made with a circular top (f) just under the greatest depression of the seat, with y its lower face flat to rest on the upper plate or disk (g) of the pedestal (it), which is cast with a rim all around to surround the top (f)t;` and from the plate or disk (g) a spindle (i) projects up through a hole in f the top and is riveted or otherwise secured above in a recess or depression cast in the seat and covered over by a plate (lo), the upper surface of which is a continuation of the curved plane ofthe seat. This cover- Aing platetk) is secured by rivets tothe seat', and the disk of the pedestal is provided with holes l`(l) through which'the riveting is effected, and through which also `water that may pass through the joints of the covering plate will be discharged.

`The pedestal is pyramidal with six or more sides `and cast hollow, so that it can fit on toa stake (m) of corresponding form driven into the ground, so that the lposition may not be affected by frost. In this way the chair can be held steadily in place orV may be removed at pleasure; Thelower part of the pedestal is cast with a molding flange (n) as van ornament and at the same time to 'form a y.sufficiently broad base 'to stand on when `not used in connection with astake. f .j

Instead of the lpyramidal pedestal the 'chair maystand on legs (o, o, 0) Fig. l,

ilo.

cast separate or lwith the plate ordisk (g). The back of the fseat is cast with a back curved inward t-o t the back.

What I claim as my invention, and desire 4 to secure by Lett-ers Patent, is Y 1. Making the seat of cast metal chairs or stools concave or dished in all directions from the rim towardv a point midway or nearly so, between the sides and nearer the back than the front to lit the anatomy of the body, and to give more support thereto,frsubstantially as described; 'and in Acombination f therewith I also claim making the seat thus formed of open work for the discharge of water, as described. y

2. I claim casting the seat with a depression in the deepest part of the concave and covering it with a cap plate, the upper sur` face of which is a continuation of the curved plane of the seat,'in combination with the plate or disk of the pedestalfmade with holes through which the cap-plate can be secured to the seat after the seat has been secured tothe spindle on which it turns,

yand alsofor the escape of water that may leak through the joints of the cap-plate,

substantially as described. x i

V3. And nally, I claim making the pedestal a hollow in combination with a stake of corresponding form drivenpin the ground, substantially as described, so that it can be held permanently in place-:and not affected u by frost or change of season. i i i JORDAN L. MOTT.
